Abstract: The electrode for reducing the power consumption and heat generation utilizes a high purified allumium plate with a certain thickness and width.  The alluminium plate is wound certain times in a form of spiral of Archimedes with certain gaps and then two terminals are attached.  An irregularity can be formed on the surface of the alluminium plate for expanding the area available for discharge.

Title: Improved pressure swing adsorption process and apparatus
Inventor: EDWARD HISCOCK W
IPC: B01D/
Filed: 1986-03-19
Granted: 1992-03-10
Abstract: In air separation and other gas separations employing pressure swing adsorption technology, reduced cycle times are achieved by an advantageous combination of simultaneous processing steps. The gas released upon cocurrent depressurization from gigher adsorption pressure is employed for provide purge purposes. Cocurrent depressurization is also carried out at an intermediate pressure level, while countercurrent depressurization is simultaneously carried out at the opposite end of the bed being depressurized to its lower desorption pressure level. An increasing pressure adsorption step is carried out.

Title: Spacer for vehicle windshield
Inventor: HEINZ KUNERT
IPC: B60J1/10
Filed: 1988-09-03
Granted: 1996-07-05
Abstract: The subject of the invention is a vehicle window in which the windowpane 1 is fitted along its upper or lower horizontal edge with a shaped bar in the form of a flange 4 directed perpendicularly to the surface of the pane. The flange 4 has a bearing surface 5 which cooperates with a bearing element 7 fixed to the support panel 2 directed substantially perpendicularly to the plane of the pane. The pane 1 fitted with the flange 4 can thus on its own by a simple positioning of the flange 4 on the bearing element 7 position itself in the window opening and be held there while the line of glue 10 sets.

Title: High quality bipolay transistor and its manufacturing method
Inventor: KIM HYEN-SU
IPC: H01L29/70
Filed: 1988-09-23
Granted: 1992-01-17
Abstract: High performance bipolar transistor is  manufactured  by  (a) forming link area for p layer (18) between intrinsic base p- layer (17) and extrinsic base p+ layer (19)  under  high  conc.  emitter area, and (b) forming a single inside connection part (24) between emitter N+ layer (22)  and  metal  layer  (29).  This  method  can prevent current leakage by minimizing collision between high conc. layers, increase junction breakdown voltage  and  improve  current amplification. And also it can simplify the manufacturing  process and so reduce the cost.

Title: Semiconductor integrated circuit
Inventor: KENIS AUSTIN
IPC: G11C27/02
Filed: 1991-04-02
Granted: 1999-06-15
Abstract: This invention relates to semiconductor integrated circuits concerned with the realisation of different value capacitive components of a semiconductor chip by means of programming control arrangements. Programmable (IC) capacitors are implemented using a capacitive multiplier technique. Programmable capacitors comprise essentially three elements, a capacitor (C1) and one or two capacitor multipliers (M1 and M2). Capacitor (C1) is connected to the output of a first buffer circuit (B1) while programmable resistors (RP1 and RP2) are connected in series between the input and output of the buffer (B1), an output being taken from the junction between the first and second programmable resistors. By this arrangement of components, the ratio of the set values of the two programmable resistors (RP2 and RP1) determines the amount by which the capacitor (C1) value is multiplied. An overall effective capacitance value equal to (RP2/RP1) x C1 may be achieved. The final effective capacitance with two multipliers (M1, M2) approximates to (RP2/RP1) x (RP4/RP3) x C1. The value of programmable resistor RP1 is adjusted in accordance with an analogue reference signal (CCV) produced by a compensating circuit (Fig 2) to compensate for the manufacturing/processing variations of capacitor C1. <IMAGE>

The saving chamber has a separating panel having a screw, a blocking plate (24), a rotatable plate. At the top of the main body a planar part having several water holes is installed. The selection of the direct suppling mode and the saving mode can be controlled by a screw cap (2) jointed with a hiding plate (13). The hiding plate has water holes jointed with a flange of water supplying pipe.
